We are good with you using the option writing premium, what is the issue is to use the loophole that exists in the system.
Assuming you write a 5000 call at 800 using MIS. YOu will receive 40,000 as premium but only around 20,000 is blocked. You will use this 40000 to write more options. This way you can run an unlimited position with just 20,000 in your account.. Usually when such things are done, we know that the trader is looking at taking a ride by putting the broker at risk. Most of us at Zerodha are traders and we can spot these very easily..
Let me ask you a straight question:
(1) If you are policy is "Not to allow premium on writing options" to be available for future trading, Why don't you include it in your policy on Margin? It is not included. The possible reason is NSE does not restrict.
(2) When you show funds available with margin in ledger in the back office,you do not reduce the available margin from the premium amount on writing options.
(3) When someone takes more position, the money available as premium from writing options is allowed automatically as it is included in the available margin. All my trades are based on margin availability as per backoffice.
(4) When you decide to square off the positions, you suddenly decide to take away these funds from available margin,and thus raise a RED Flag.
(5) Please let me know,if 1 to 4 is correct.
(6) If say "No", I shall raise many more queries.
(7) If you say"Yes", then tell me how are you justified in squaring the positions as you have changed the very basis of available/required margin.
Please be specific and do not try to mislead the forum by raising hypothetical situations.
